Detecting apparatus for monitoring culture broth in bio-reactor

Abstract

A detecting apparatus is disclosed, that comprises plural measurement devices with respective sensors and a support for holding the measurement devices in such a manner that the individual sensors contact a culture broth, the turbidity, dissolved oxygen, dissolved carbon dioxide the temperature, pH, and so forth of the culture broth being obtained by the measurement devices.

What is claimed is: 
     
       1. A detecting apparatus for monitoring a culture broth in a bio-reactor, comprising: plural measurement devices with respective individual sensors,   a housing for covering said measurement devices having at least one passage for the culture broth; and   a holding means for holding said measurement devices in such a manner that the individual sensors contact the culture broth.   
     
     
       2. The detecting apparatus as set forth in claim 1, wherein said measurement devices contain at least one device selected from the group consisting of a turbidity detector, a dissolved oxygen detector, a dissolved carbon dioxide detector, a thermometer, and a pH detector.   
     
     
       3. The detecting apparatus as set forth in claim 1, wherein said housing is hollow and said at least one passage comprises an opening portion. 
     
     
       4. The detecting apparatus as set forth in claim 3, wherein the opening portion of said housing has a mesh for preventing bubbles from entering the inside of said housing.   
     
     
       5. A detecting apparatus for monitoring a culture broth in a bio-reactor, comprising: plural measurement devices with respective sensors;   a hollow housing for said measurement devices having at least one passage comprising an opening portion through which the culture broth passes; and   a holding means for holding said measurement devices in such a manner that the sensors contact the culture broth.
